This advisory provides information on advisory material related to the standards and procedures contained in the Airworthiness Manual (AWM). Updated lists of all current and cancelled AMAs are presented in Appendix A and B respectively. FAA Advisory Circulars excluded for use with the AWM are listed in Appendix C.

Information usually addresses issues or non regulatory material which may be of interest; in a few cases it is used to advise industry on the criteria or the requirements that the Department will apply in specific certification cases in the form of Special Conditions - Airworthiness.

Interpretations are used to advise industry on current policies, and in certain cases the Department reading of current requirements, pending the results of international harmonization.

Means of compliance are recommended means of complying with the requirements contained in the AWM, in particular with Canadian additional technical conditions (Canadian variants). In this case the content of the advisory is not binding on the public. The applicant may elect to follow an alternate method, provided that the proposed means is acceptable to the Department.

Advisory material may be presented in two forms: as a short and concise "Information Notes" imbedded in the text right after the affected standards, or as a separate document, i.e., "Airworthiness Manual Advisory" (AMA), when the information is too conspicuous to be published within the standards.

The current Airworthiness Manual Advisory (AMA) material for the series 500 AMAs, the Design Standards have been, as of December 1, 2004, renamed and reformatted as Advisory Circulars (AC). The conversion is strictly a format and number change while the contents remain unchanged. The conversion of advisory material from AMA to AC is undertaken to further harmonize the Canadian Aviation Regulatory system with the Federal Aviation Administration Regulations and the new European Aviation Safety Agency Certification Specifications. Not only will this conversion bring us closer to harmonization with the FAA and EASA but will also allow harmonization of the Aircraft Certification branch advisory material with the other branches of Transport Canada Civil Aviation that are currently using ACs.

Appendix B of this AMA provides a list of replacement AC numbers for the previously existing AMA numbers.

The AC Index to replace AMA 500/00 has been established and contains all of the current ACs with their new corresponding AC number that were previously published as AMAs. That Index is SI No. GEN-001. AMA 500/00 will continue to be published until the all the AMAs for Delegation and Certification Procedures, Recreational Aviation and Maintenance and Manufacturing are converted to ACs or for as long they continue to be relevant.

3. AMA Numbering System

AMA numbers are assigned to correspond to a subject area of the AWM according to the following system:

(a)Series 500 AMAs

AMAs containing miscellaneous or general information or addressing subjects applicable to more than one Chapter of the AWM will be issued in the 500 Series, e.g. AMA 500/n A;

where: n = sequential number (1, 2, 3 etc.)

A = sequential amendment status (A, B, C etc.)

Information Note:

Originally the 500 Series AMAs had a speciality ID letter (A to G), following the number 500. This system has been discontinued.

Staff Instruction (SI) GEN-002 should be consulted for formatting and numbering of new Advisory Circulars (AC).

4. Foreign Advisory Material

Transport Canada also reviews advisory material published by the Federal Aviation Administration (FAA) of the USA and the Joint Aviation Authorities (JAA), and may accept this material for use with the design standards contained in the Airworthiness Manual, when they are not conflicting with Canadian regulations, standards, policies, interpretations and advisory material.

(a)FAA Advisory Material

Except when specifically excluded in Appendix C of this document, FAA ACs addressing the adopted design standards of FAR 23, 25, 27, 29, 31, 33 and 35, as well as some related ACs in the series 20, 43, 90, 91, 120 and 121, are considered acceptable for use with the Airworthiness Manual subject to the following:

(i) Only the airworthiness content is accepted.

(ii) Any reference to "FAA Administrator" and "Administration" will read the "Minister".

(iii) Any reference to FAR sections (Part 23 to 35) will read as sections of the corresponding AWM Chapter (523 to 535).

(iv) No advisory circular can modify or change a Canadian standard.

(v) Any reference to FAA regulations which have not been adopted in Canada may be allowed only if the foreign regulations are not in conflict with the Canadian Aviation Regulations (CARs).

(vi) FAA operational regulations do not apply in Canada and shall be replaced by reference to the applicable CARs.

(vii) Canadian equivalents will not be substituted where statements of fact are being made, e.g. "FAA does not require in FAR 91.125 etc."

FAA Advisory Circular exclusions will, as of December 1, 2004 be provided in SI No. GEN-001 published by the Aircraft Certification branch.

Information Note:

Federal Aviation Administration Advisory Circulars (ACs) are available (in English only) by mail order from:

The JAA advisory material accepted for use with the design standards of Chapter 522, Gliders and Powered Gliders, and Chapter 523-VLA, Very Light Aeroplanes, are listed respectively in AMA 522/1 and AMA 523-VLA/1, as revised from time to time.

See Appendix B of this AMA for the replacement AC numbers of AMA 522/1 and AMA 523-VLA/1.
